truncdist: Truncated Random Variables

A collection of tools to evaluate probability density
functions, cumulative distribution functions, quantile functions
and random numbers for truncated random variables. These functions are
provided to also compute the expected value and variance. Nadarajah
and Kotz (2006) developed most of the functions. QQ plots can be produced.
All the probability functions in the stats, stats4 and evd
packages are automatically available for truncation..
